Nursing caries is a specific form of rampant decay of the primary teeth of infants. The distinguishing features of rampant caries are: (1) many teeth are involved; (2) lesion development is rapid; and (3) carious lesions occur on surfaces generally considered to be at low risk to decay, such as proximal surfaces of mandibular anterior teeth, facial surfaces of maxillary anterior teeth, and ling...

The report presents examples of successful cases of autotransplantation of ectopic teeth as donor in the treatment of clinically missing maxillary anterior teeth in young patients. The transplanted teeth were either severely ectopic, inverted, rotated or in an unfavourable position that they are commonly sacrificed as a result. Details of surgical technique as well as clinical and radiographic ...

OBJECTIVES/HYPOTHESIS Bony manipulation near the nasal spine or maxillary crest trimming can predispose teeth to injury during septorhinoplasty, especially when there is an aberrant vascular supply or a highly situated root apex in the premaxilla. STUDY DESIGN Prospective cross-sectional study. METHODS A prospective cross-sectional study was carried out on 438 teeth (maxillary incisors and ...

PURPOSE The purpose of this study was to determine the effect of changes in the horizontal plane angle on the mesiodistal width ratios of the maxillary anterior teeth during the acquisition of frontal view photographs, derive these ratios for Korean adults on the basis of the data obtained, and analyze them using the Golden Proportion as a reference. MATERIALS AND METHODS In experiment I, 30 ...

Failure of eruption of primary teeth can be considered rare, especially in maxillary anterior teeth. The problem can be either mechanical obstruction of eruption or a failure of the eruption mechanism. This case report presents failure of eruption of the maxillary right deciduous central incisor in a 4-year-old girl. The unerupted primary tooth was removed surgically. The histological finding r...

AIMS The aim of this study was to evaluate the stress on the abutment teeth and framework ina unilateral maxillary defect which was restored by an obturator retained by resin-bonded extra coronal attachment. METHODS A three-dimensional finite element model of the human unilateral maxillary defect was constructed. Traditional obturator framework with four casting circumferential clasp was esta...

The prosthetic rehabilitation of patients with an edentulous maxilla opposing mandibular anterior natural teeth is one of the most challenging situations that a clinician encounters. Occlusal forces from the opposing natural teeth may cause fractures in the maxillary prosthesis and also result in residual ridge resorption of the edentulous maxilla. Prosthodontists try overcoming this Combinatio...

The purpose of this study was to quantify the treatment effects of distalization of the maxillary and mandibular molars using microscrew implants. The success rate and clinical considerations in the use of the microscrew implants were also evaluated. Thirteen patients who had undergone distalization of the posterior teeth using forces applied against microscrew implants were selected. Among the...

Tooth pulp atrophy occurs with increasing age. An age estimation procedure using dental cone beam computed tomography (CBCT) imaging was developed. Clinical dental CBCT images of 60 patients (aged from 20 to 80 years) were evaluated. The ratio of the cross-sectional area of the pulp cavity to the cross-sectional area of the tooth (pulp cavity ratio) was calculated. The pulp cavity ratio in the ...

Trauma to anterior teeth is common and requires accurate diagnosis and thorough treatment planning. The maxillary incisors are often affected during injury to the face because of their normal labial projection inflicting damage to the crowns. Multidisciplinary treatment approach is important for aesthetic and functional rehabilitation of anterior teeth with crown fracture. The purpose of this a...
